I IMPROVEMENT IN WOVEN TRIMMING.

| 'The Schedule referred to in these Letters Patent and making part 0f the same.

To all whom it may concern:

vmont of two or more threads or cords, partly woven into -the ribbon or trimming, and partly laid outside the material in such a`manner that by-rnoving or sliding the material ou the threads or cords, the same will lay in regular folds or plaits usually called box plaitnur.

cFigure I represents a sideelevation of a piece of trimming embodying my invention;

Figurell is a section of the same;

Figure III-drepresents the same only partly drawn Figures LV and V represent the same in section and front view drawn together 0r folded in regular box plaiting.

In the accompanying drawingrepresents a. piece of a ribbon or trimming, which may4 be woven in any desired style or pattern, either plain or fancy weaving.

the warp for the same is arranged in the loom,two or more threads or c ords A and B are placed in the same, ot' heavier or stronger material than thewarp for the desired article.

Thesethreads or cords are placed either near the center, or the same maybe placed nearer to the one or to the other yedge of the ribbon, or band according to the description of the trimming desired.

The thread orcord A is interwoven with the weft as the spaces m and u in the usual manner, while at the spaces x, between the same, this thread or cord lays free upon ther front snif-ace of the material.

The thread or cord B is interwoven with the weft at the' spaces e: and w in the usual manner, while at the spaces s, between the same,tl1isl thread or cord lays free upon the back surface of the material.

The length ofthe spaces m where the cord A is interwoven with the material is regulated and corresponds with the desired width of the plait, while the length of the spaces n, where the cord A is interwoven with the material corresponds with the desired width the plaits are required to be apart when folded.

The spaces w and fv, where the cord B is interwoven with the material, are regulated in such a manner as to cause that part of the material which is folded under to lay regular and to secure the same against the back perfectly flat and smooth.

When the band or ribbon which is to form the box plait trimming is very wide, the cord B may be arranged in the center, having a cord, Aon each side, or several more cords may be'arranged.

, After the band or ribbon is finished, the cords A and B are fastened at one end of the piece, and the material moved upon the cords by drawing the same through the material, until the spaces m and n meet, whereby the regular box plait will be formed.

The spaces a: by this operation will be folded under, so that the spaces t and w meet, and lay perfectly smooth against the under side of the material, and are thus securely fastened without the necessity of sewing, or any other manner of fastenings.

do not claim, broadly, weaving one or more loose threads into the material, capable of being drawn or gathered up; but

VVbat l claim as my invention, and desire to secure by Letters Patent, is-

The arrangement of cords A and B in the warp, and combined with the weft at intervals as described, and so that the fabric, when moved on such cords, will be formed into box plaits.
